What's interesting is that this build's Amazing Arena actually has a light switch at least on the first level, near the first clock (just hold right when you start the level to hit it). The hologram Eggman is also functional and can hurt you with his fists. The next build with a switch near that first clock is the Jan 19 build, and even then its hologram's fists don't cause damage and instead just flail around for humorous effect.
